In reply to gali:
The only place I imagine you'll get winter QMDs now is on the high Cairngorm plateau going in from the north. Did Beinn Mheadhoin and Ben Macdui from Cairngorm ski centre on Sunday gone and was on snow 80-90% of the time. I would say for the route we took the snowline was 700, being solid cover above 1000. We could see south facing slopes were pretty thin even above 1000 (Bynack More looked almost completely clear). IMO aside from the route we did, a Braeriach/Cairn Toul route would be the only solid Winter QMDs your likely going to get. You'll definitely get winter days in elsewhere, but I doubt they would be ones you'd want to present in your 40 at assessment.
